| DESCRIPTION |
The Lunar Reconnaissance Orbiter Camera (LROC) consists of two narrow-angle camera components (NACs), a wide-angle camera component (WAC), and a common Sequence and Compressor System (SCS). Each NAC has a 700 mm focal length Cassegrain (Ritchey-Chretien) telescope that images onto a 5064-pixel CCD line-array providing a cross-track field- of-view (FOV) of 2.86 degrees. The WAC has two lenses imaging onto the same 1024 x 1024 pixel, electronically shuttered CCD area-array, one imaging in the visible/near infrared (VIS), and the other in the Ultraviolet (UV). In monochrome mode, 1024 x 14 pixels are read out in one visible band (645 nm). In color mode, only the center 704 x 14 visible pixels and 512 x 16 UV pixels, which are binned to 128 x 4, are read out for each band. the SCS commands individual image acquisition by the NACs and WAC from a stored sequence delivered to the SCS by the LRO spacecraft, and losslessly compresses the NAC and WAC data as they are read out and passed to the spacecraft data system.
